Abstract: A vehicle steering system comprises a source of fluid, a hydraulic steering motor actuatable to effect vehicle steering, and a steering control valve in fluid communication with the source of fluid and with the steering motor. The steering control valve is operable to direct fluid from the source of fluid to the steering motor. A metering mechanism is connected in fluid communication with the steering control valve and the steering motor. The metering mechanism is manually operable in accordance with the operator's demand for steering, and a hydraulic system is responsive to demand for steering fluid by the metering means to increase the output flow of the fluid from the source of fluid to the metering means at a pressure sufficient only to effect steering action against a variable load.

Abstract: A permanent magnetic system for adhesion purposes, specifically a clamping plate, comprising individual permanent magnets inserted into a ferro-magnetic housing and a cover plate of ferro-magnectic material covering the permanent magnets and the housing and used as an adhesion surface, said cover plate seating directly on the pole surfaces of the permanent magnets and having a thickness so dimensioned in relation to the magnetic flux of force of the permanent magnets that it provides a magnetic stray field exceeding the magnetic saturation.  In this way, the cover plate located in a partly magnetic short circuit represents on the total pole surface of the permanent magnet system a directly magnetic connection to the blank, whereby its magnetic stray field, magnetically shorted via the blank, thus is included into the existing partial magnetic short circuit.  Because the magnetic flux of force is effectively made to possess and optimal value in the magnetic short circuit, a sure guaranty is created for the desired adhesion.

Abstract: A method and apparatus for controlling the pressure of gas sealed in a coaxial communication cable so as to maintain the dielectric constant and hence electrical length thereof constant independent of temperature or the leakage of insulating gas sealed therein. Electrical signals are produced representing the temperatures of the gas sealed in the cable and the temperature of a reference gas sealed in a closed container as well as signals representing the pressures thereof. The two temperature signals are compared and the temperature of the reference gas adjusted in accordance therewith by a constant temperature bath. The two pressure signals are compared and gas is fed into the cable in accordance therewith. The temperatures of the cable and the reference gas are maintained at the same values as are the pressures thereby maintaining the density and hence dielectric constant of the gas sealed in the coaxial cable constant at all times.
